What is Infineon Technologies?
Updated
Infineon Technologies is a semiconductor and system solutions company. Its website, infineon.com, organizes products around chips and subsystems that go into automotive, industrial, consumer, and security applications — including microcontrollers, sensors, power management ICs, memories, USB, Bluetooth, WiFi, and LED drivers. If you are trying to identify whether Infineon makes a part for your design, the fastest path is to start from the product category list rather than from an application page.
What Infineon actually sells
The site's own navigation lists these product families:
- Microcontrollers — AURIX™ TriCore™ MCUs, PSoC™ MCUs, TRAVEO™ T2G MCUs, XMC™ MCUs, legacy MCUs, and MOTIX™ motor control SoCs/SiPs
- Power — AC-DC conversion, DC-DC converters, IGBTs, gallium nitride (GaN), gate driver ICs, intelligent power modules, diodes and thyristors (Si/SiC), eFuses, Class D audio amplifiers, contactless power and sensing
- Sensors — listed as a top-level category alongside power and microcontrollers
- Memories — NOR flash, F-RAM, nvSRAM, PSRAM, SRAM, embedded flash IP, Flash+RAM MCP, radiation-hardened and high-reliability memory, wafer and die solutions
- Security and smart card solutions — including payment-related offerings such as smart card solutions, wearable payments, and biometric payment
- Wireless connectivity — Bluetooth and WiFi
- USB — Universal Serial Bus products
- Automotive Ethernet — PHY and switches for in-vehicle networking
- Isolation — digital isolators and isolated industrial interfaces
- Clocks and timing — CYPRESS™ buffers, clock generators, oscillators
- ESD and surge protection — low-capacitance, multi-purpose, and high-linearity ESD protection, plus surge protection devices
- High reliability — defense, space, NewSpace, and custom high-reliability services
- ASIC — ASIC solutions and SoC/SiP/FPGA offerings
- Small signal transistors and diodes, battery management ICs, evaluation boards, and transceivers
The breadth matters: Infineon is not a single-product vendor. A design decision usually starts by picking the category that matches your function, then narrowing to a family.
How the site is structured for finding a part
The main menu separates four things that are easy to confuse:
| Section | What it is for |
|---|---|
| Products | The catalog of chips and subsystems, browsable by category |
| Applications | Use-case entry points, e.g. security and payment solutions |
| Design Resources | Technical material to support a design |
| Support & Training | Help and learning content |
There are also Search Tools, Technology Packages, Product Information, and Ordering entries under the product area. If you already know a part number, search is faster than browsing. If you only know the function, browse the category.
Developer support and design resources
Infineon provides a Developer Support area and a Design Resources section. The site also references myInfineon, an account system with a dashboard, notifications, bookmarks, online orders, cases, myICP, and a profile center. Logging in is required for those account features — the public product and application pages are visible without it.
One practical note: myICP appears as a distinct area from the general account dashboard, which suggests some technical content sits behind a separate program rather than the standard login.
When Infineon is the right place to look
- You need an MCU for automotive or industrial control (AURIX™, TRAVEO™, XMC™, PSoC™).
- You need power switching or conversion — Si, SiC, or GaN devices, gate drivers, or modules.
- You need non-volatile memory that is not standard flash (F-RAM, nvSRAM, radiation-hardened memory).
- You need a security or payment chip, including smart card or wearable payment form factors.
- You need wireless connectivity (Bluetooth, WiFi) or USB.
- You need automotive Ethernet PHY or switches.
- You need high-reliability or space-grade parts.
If your requirement is a general-purpose logic part or a commodity passive component, the category list above is the check — those are not among the listed families.
What to verify before committing
Product pages on infineon.com are the authoritative source for part numbers, packages, and ordering information. Pricing is not stated in the material reviewed here, so treat cost as something to confirm through the ordering path or a distributor rather than assuming. Likewise, availability and lifecycle status should be checked per part, since the catalog includes both current families and legacy MCUs.
